Caution: Acrylamide is a potent neurotoxin and absorbed through the skin. The effects of acrylamide are cumulative. Although polyacrylamide is suspected to be nontoxic, it should be handled with great care because of the possibility that it might contain small quantities of unpolymerized acrylamide.

4-(2-AminoEthyl)-BenzeneSulfonyl Fluoride HCl
C₈H₁₀FNO₂S·HCl
M.W.: 239.69

Less toxic alternative to PMSF, pH stable.
AEBSF irreversibly inactivates thrombin and other serine proteases (e. g. chymotrypsin, kallikrein, plasmin, proteinase K, trypsin) by sulfonylation of a functional group in the active center of the enzyme. AEBSF (LD50 oral, mouse 2.8g/kg) is a substantially less toxic substitute for PMSF and DFP.

For the preparation of 1 Liter liquid for LB agar plates weigh 10 g tryptone, 5 g yeast extract, 5 g NaCl and 15 g agar. Add 1 mL 1 N NaOH to the dissolved powder. The medium will be autoclaved for 25 minutes. At a temperature of ~50°C, it is still liquid and additives (e. g. antibiotics) can be added. If 32 to 40 mL LB agar per plate are used, one liter will result in approx. 25 to 30 plates. Freshly poured plates cool down with a slightly opened lid and turn them upside down when stored at +4°C.
